A man has appeared in court and admitted making racially-offensive Twitter comments about footballer Fabrice Muamba, who collapsed after suffering a cardiac arrest during an FA Cup tie.
Liam Stacey was in the dock at Swansea Magistrates Court, sitting at the Crown Court on Monday, charged with a racially-aggravated public order offence.
The 21-year-old, from Pontypridd, South Wales, entered a guilty plea and was bailed to return to court on March 27.
The comments appeared on the Twitter account @liamstacey9, which has since been taken down.
While the feed was still visible, comments claimed that his account had been hacked.
Other users of the site responded with outrage to the remarks.
Muamba , 23, was taken to hospital after suffering what appears to have been a cardiac arrest on the pitch before 36,000 spectators on Saturday night.
He remains in a critical condition but is showing signs of improvement , a joint statement from Bolton Wanderers and the London Chest Hospital has said.
The footballer's illness has prompted a wave of support and prayers from both fans and others in the world of football.
Both Swansea University and Treorchy RFC, where Stacey is believed to have played rugby, have made statements condemning the comments on his Twitter feed.
"We disassociate ourselves from any racist remarks," a Swansea University spokesman said.
Treorchy RFC said: "The club wishes to completely disassociate itself from these comments and will be carrying out a full investigation into this matter.
"The club values its position and reputation within the local community and the wider rugby community and at all times encourages our members to treat others with dignity and respect."
